How to Resize PDF Pages (A4, Letter, and More)
Published September 4, 2026 · 3 min read

Frequently asked questions
The "contain" fit mode scales content proportionally without stretching, adding margin as needed; choose that if distortion is a concern.
Yes — set the target orientation alongside the size, and the tool handles both in one pass.
No — cropping trims part of the page away; resizing scales the entire page (and its content) to fit a new page size.
Since scaling happens locally, you can standardize a whole folder of mixed-size PDFs to one paper format without uploading any of them.
